Quad Bikes Cornwall

What are tourist attractions and activities in Cornwall (United Kingdom)?
Me and a couple of friends they are planning a long bike ride St. Ives in Cornwall pleasant umpteenth WST for a week in June. Do any of you guys / girls know what we do when we get there? I was told quads is a circuit that sounds fun, and I like to go to Tintagel Castle, but I'm stuck for ideas. Must be done. Please help.
Hello, St Ives is a great place, see below on what to do. St. Ives Museum, Porthmeor Beach – Open from late May to September. It has a more fascinating insight 200 years of history villages, it is very good if this is of interest. Tregenna Castle Hotel Golf Course – A course in a park located in the magnificent grounds of Tregenna Castle Hotel, with narrow streets and small greens and fabulous views of the bay of St. Ives. St Ives Sailing Club – St Ives Bay offers a wonderful opportunity to experience sailing sea in the relative safety of the Bay of St. Ives. Before your holiday that I would call a tourist information center and get sent to you information. Hope this helps
